Age- and sex-related differences in use of guideline-recommended care and mortality among patients with incident heart failure in Denmark.

BACKGROUND: data are sparse on age- and sex-related differences in use of guideline-recommended care and subsequent mortality among patients with heart failure (HF). METHODS: we identified 24,308 incident patients with a verified primary diagnosis of HF recorded during 2003-2010 in the Danish Heart Failure Registry. The registry monitors guideline-recommended processes of care: echocardiography, New York Heart Association Classification, treatment with angiotensin converting enzyme inhibitors/angiotensin II receptor blockers, betablockers, physical training and patient education. RESULTS: older age was associated with lower use of recommended processes of care. Relative risk (RR) for receiving processes of care varied for men >80 years from 0.52 to 0.91 compared with men ≤65 years. Corresponding RRs among women >80 years varied from 0.55 to 0.89 compared with women ≤65 years. Older age was as expected associated with higher 1 year mortality (32.6% among men >80 years versus 5.4% among men ≤65 years and 33.8% among women >80 years versus 6.6% among women ≤65 years). The corresponding hazard ratios (HRs) were 4.54 (95% CI 3.93-5.25) and 4.08 (95% CI 3.51-4.75) for the oldest versus youngest men and women, after adjustment for patient characteristics. Adjustment for differences in care lowered HRs among the oldest age groups (adjusted HR 3.87 for men and 3.48 for women, respectively). The findings were also confirmed when stratifying the patients according to left ventricular ejection fraction ≤40% and >40%. CONCLUSION: older patients with HF were less likely to receive guideline-recommended processes of care, irrespective of sex. Lower level of care may contribute to an excess mortality observed among the older patients.

Trends in quality of care among patients with incident heart failure in Denmark 2003-2010: a nationwide cohort study.

BACKGROUND: The treatment of heart failure (HF) is complex and the prognosis remains serious. A range of strategies is used across health care systems to improve the quality of care for HF patients. We present results from a nationwide multidisciplinary initiative to monitor and improve the quality of care and clinical outcome of HF patients using indicator monitoring combined with systematic auditing. METHODS: We conducted a nationwide, population-based prospective study using data from the Danish Heart Failure Registry. The registry systematically monitors and audits the use of guideline recommended processes of care at Danish hospital departments treating incident HF patients. We identified patients registered between 2003 and 2010 (n = 24,504) and examined changes in use of recommended processes of care and 1-year mortality. RESULTS: The use of the majority of the recommended processes of care increased substantially from 2003 to 2010: echocardiography (from 62.7% to 90.5%; Relative Risk (RR) 1.45 (95% CI, 1.39-1.50)), New York Heart Association classification (from 29.4% to 85.5%; RR 2.91 (95% CI, 2.69-3.14)), betablockers (from 72.6% to 88.3%; RR 1.23 (95% CI, 1.15-1.29)), physical training (from 5.6% to 22.8%; RR 4.04 (95% CI, 2.96-4.52)), and patient education (from 49.3% to 81.4%; RR 1.65 (95% CI, 1.52-1.80)). Use of ACE/ATII inhibitors remained stable (from 92.0% to 93.2%; RR 1.01 (95% CI, 0.99-1.04)). During the same period, 1-year mortality dropped from 20.5% to 12.8% (adjusted Hazard Ratio 0.79 (95% CI, 0.65-0.96). CONCLUSIONS: Use of guideline recommended processes of care has improved among patients with incident HF included in the Danish Heart Failure Registry between 2003 and 2010. During the same period, a decrease in mortality was observed.

The Danish Heart Failure Registry: A Validation Study of Content.

Background: The Danish Heart Failure Registry (DHFR) is a clinical quality database established to monitor and improve the quality of heart failure (HF) care in Denmark. Objective: We examined the validity of the content of the DHFR. Methods: In a random sample of patients registered in DHFR between the 1st of January 2016 to the 31st of December 2018, we determined the agreement between the information entered in the database and information in the medical records regarding 1) content; 2) sensitivity; 3) specificity; 4) positive predictive values (PPV) as well as negative predictive values (NPV) of all patient characteristics and performance measures obtained in the DHFR. Results: The study population included 453 patients. In general, the content of the DHFR was accurate. Patient characteristics showed high PPV between 93.0% and 99.5% for all variables. Sensitivity ranged from 81.0% to 95.2%, specificity from 79.8% to 99.5% and NPV ranged from 81.4% to 99.0%. The pharmacological performance measures showed high agreement regarding sensitivity (77.4% to 98.6%) and PPV (84.0% to 94.0%). Further, the specificity ranged from 66.7% to 98.0% and NPP ranged from 90.1% to 96.5%. For the non-pharmacological performance measures, patient education showed high sensitivity (98.0%, 95% CI 96.1-99.1) and PPV (94.9% CI: 93.0-96.3), whereas referral to exercise training had a lower sensitivity of 77.8% (CI: 71.6-83.1) and a PPV of 74.5% (CI: 69.6-78.6). Conclusion: Overall, the Danish Heart Failure Registry have a high degree of completeness and validity, making it a valuable tool for clinical epidemiological research in HF.

Cardiac rehabilitation for patients with heart failure: association with readmission and mortality risk.

AIMS: To examine the temporal trends and factors associated with national cardiac rehabilitation (CR) referral and compare the risk of hospital readmission and mortality in those referred for CR versus no referral. METHODS AND RESULTS: This cohort study includes all adult patients alive 120 days from incident heart failure (HF) identified by the Danish Heart Failure Registry (n = 33 257) between 2010 and 2018. Multivariable logistic regression models were used to assess the association between CR referral and patient factors and acute all-cause hospital readmission and mortality at 1 year following HF admission. Overall, 46.7% of HF patients were referred to CR, increasing from 31.7% in 2010 to 52.2% in 2018. Several factors were associated with lower odds of CR referral: male sex [odds ratio (OR): 0.85; 95% confidence interval: 0.80-0.89], older age, unemployment, retirement, living alone, non-Danish ethnic origin, low educational level, New York Heart Association (NYHA) class IV vs. I (OR: 0.75; 0.60-0.95), left ventricular ejection fraction >40%, and comorbidity (stroke, chronic kidney disease, atrial fibrillation/flutter, and diabetes). Myocardial infarction, arthritis, coronary artery bypass grafting, percutaneous coronary intervention, valvular surgery, NYHA class II, and use of angiotensin-converting enzyme inhibitors were associated with higher odds of CR referral. CR referral was associated with lower risk of acute all-cause readmission (OR: 0.92; 0.87-0.97) and all-cause mortality (OR: 0.65; 0.58-0.72). CONCLUSION: Although increased over time, only one in two HF patients in Denmark were referred to CR in 2018. Strategies are needed to reduce referral disparities, focusing on subgroups of patients at highest risk of non-referral.

Association between process performance measures and 1-year mortality among patients with incident heart failure: a Danish nationwide study.

Aims: To examine the association between fulfilment of performance measures supported by clinical guidelines recommendations and 1-year mortality among patients with incident heart failure (HF) in Denmark. Methods and results: A nationwide population-based follow-up study based on the Danish Heart Failure Registry. All Danish hospital departments caring for patients with HF. We identified 24 308 in- and outpatients diagnosed with HF from 2003 to 2010. Quality of care was defined as receiving the guideline recommended processes of care: use of echocardiography, New York Heart Association classification, treatment with angiotensin-converting-enzyme inhibitors/angiotensin-II-receptor blocker, beta blockers, physical training, and patient education. Main outcome measure is 1-year mortality. We used multiple imputation and multivariable Cox proportional hazard regression to compute hazard ratios (HRs) for 1-year mortality adjusted for potential confounding factors. Within 1 year, 17.1% of the patients died and the adjusted HRs ranged from 0.61 [95% confidence interval (CI) 0.55-0.67] for patient education to 0.99 (95% CI 0.90-1.10) for beta blocker therapy. The association between meeting more performance measures and 1-year mortality appeared to follow a dose-response pattern: using 0-25% of fulfilled measures as reference, patients who fulfilled 76-100% of the performance measures had an adjusted HR of 0.43 (95% CI 0.38-0.48), while the adjusted HR was 0.96 (95% CI 0.86-1.07) for patients who fulfilled between 26% and 50% of the performance measures. Conclusion: Meeting process performance measures, which reflect care in concordance with clinical guideline recommendations, was associated with substantially lower 1-year mortality among patients with incident HF.

The Danish Heart Failure Registry.

AIM OF DATABASE: The aim of the Danish Heart Failure Registry (DHFR) is to monitor and improve the care of patients with incident heart failure (HF) in Denmark. STUDY POPULATION: The DHFR includes inpatients and outpatients (≥18 years) with incident HF. Reporting to the DHFR is mandatory for the Danish hospital departments treating patients with incident HF. Final decision to register a patient in the DHFR is made by a cardiologist to ensure the validity of the diagnosis. Approximately 42,400 patients with incident HF were registered in the DHFR in July 2015. MAIN VARIABLES AND DESCRIPTIVE DATA: The main variables recorded in the DHFR are related to the indicators for quality of care in patients with incident HF: performance of echocardiography, functional capacity (New York Heart Association functional classification), pharmacological therapy (angiotensin converting enzyme/angiotensin II antagonist inhibitors, beta-blockers, and mineralocorticoid receptor antagonist), nonpharmacological therapy (physical training, patient education), 4-week readmission rate, and 1-year mortality. Furthermore, basic patient characteristics and prognostic factors (eg, smoking and alcohol) are recorded. At the annual national audit in the DHFR, the indicators and standards for good clinical quality of care for patients with HF are discussed, and recommendations are reported back to clinicians to promote quality improvement initiatives. Furthermore, results and recommendations are communicated to the public in an annual report. All standards for the quality indicators have been met at a national level since 2014. Indicators for treatment status 1 year after diagnosis are under consideration (now prevalent HF). CONCLUSION: The DHFR is a valuable tool for continuous improvement of quality of care in patients with incident HF in Denmark. Furthermore, it is an important resource for the Danish registry-based HF research.

The Danish Prostate Cancer Database.

AIM OF DATABASE: The Danish Prostate Cancer Database (DAPROCAdata) is a nationwide clinical cancer database that has prospectively collected data on patients with incident prostate cancer in Denmark since February 2010. The overall aim of the DAPROCAdata is to improve the quality of prostate cancer care in Denmark by systematically collecting key clinical variables for the purposes of health care monitoring, quality improvement, and research. STUDY POPULATION: All Danish patients with histologically verified prostate cancer are included in the DAPROCAdata. MAIN VARIABLES: The DAPROCAdata registers clinical data and selected characteristics for patients with prostate cancer at diagnosis. Data are collected from the linkage of nationwide health registries and supplemented with online registration of key clinical variables by treating physicians at urological and oncological departments. Main variables include Gleason scores, cancer staging, prostate-specific antigen values, and therapeutic measures (active surveillance, surgery, radiotherapy, endocrine therapy, and chemotherapy). DESCRIPTIVE DATA: In total, 22,332 patients with prostate cancer were registered in DAPROCAdata as of April 2015. A key feature of DAPROCAdata is the routine collection of patient-reported outcome measures (PROM), including data on quality-of-life (pain levels, physical activity, sexual function, depression, urine and fecal incontinence) and lifestyle factors (smoking, alcohol consumption, and body mass index). PROM data are derived from questionnaires distributed at diagnosis and at 1-year and 3-year follow-up. Hitherto, the PROM data have been limited by low completeness (26% among newly diagnosed patients in 2014). CONCLUSION: DAPROCAdata is a comprehensive, yet still young clinical database. Efforts to improve data collection, data validity, and completeness are ongoing and of high priority.

The Danish Cardiac Rehabilitation Database.

AIM OF DATABASE: The Danish Cardiac Rehabilitation Database (DHRD) aims to improve the quality of cardiac rehabilitation (CR) to the benefit of patients with coronary heart disease (CHD). STUDY POPULATION: Hospitalized patients with CHD with stenosis on coronary angiography treated with percutaneous coronary intervention, coronary artery bypass grafting, or medication alone. Reporting is mandatory for all hospitals in Denmark delivering CR. The database was initially implemented in 2013 and was fully running from August 14, 2015, thus comprising data at a patient level from the latter date onward. MAIN VARIABLES: Patient-level data are registered by clinicians at the time of entry to CR directly into an online system with simultaneous linkage to other central patient registers. Follow-up data are entered after 6 months. The main variables collected are related to key outcome and performance indicators of CR: referral and adherence, lifestyle, patient-related outcome measures, risk factor control, and medication. Program-level online data are collected every third year. DESCRIPTIVE DATA: Based on administrative data, approximately 14,000 patients with CHD are hospitalized at 35 hospitals annually, with 75% receiving one or more outpatient rehabilitation services by 2015. The database has not yet been running for a full year, which explains the use of approximations. CONCLUSION: The DHRD is an online, national quality improvement database on CR, aimed at patients with CHD. Mandatory registration of data at both patient level as well as program level is done on the database. DHRD aims to systematically monitor the quality of CR over time, in order to improve the quality of CR throughout Denmark to benefit patients.

[Preoperative delay in patients with peptic ulcer perforation: a clinical audit from the Danish National Indicator Project]. / Praeoperativt delay hos patienter med perforeret ulcus: en klinisk audit fra Det Nationale Indikatorprojekt.

INTRODUCTION: Mortality following perforated peptic ulcer in Denmark is nearly 30%. Delayed surgery is a prognostic factor, but only half of the patients are operated within six hours of perforation - a predefined quality of care criterion in The Danish National Indicator Project. A clinical audit was conducted to investigate possible reasons. MATERIAL AND METHODS: All patients (n = 89) surgically treated for peptic ulcer perforation in six university hospitals in Denmark over a period of one year were included. The association between a number of predefined variables related to the internal organisation of health care, the patient's pathological picture and the quality of treatment given, and a preoperative delay of at least 6 hours was examined using modified Poisson regression analyses. RESULTS: The following variables were associated with a preoperative delay = 6 hours: 1) out of hospital versus in hospital perforation (adjusted relative risk (RR) 1.87; 95% confidence interval (CI) 0.86-4.05), 2) no classical clinical symptoms of ulcer perforation (adjusted RR with peritonism 0.32; 95% CI 0.14-0.73), 3) first physician attendance later than median time, i.e. > 25 minutes after debut (adjusted RR 2.78; 95% CI 1.32-5.87), 4) first attendance not by senior physician (adjusted RR 1.97; 95% CI 0.95-4.05) and/or senior physician not called in (adjusted RR 2.53; 95% CI 1.12-5.75), and 5) oxygen saturation not monitored upon admission (adjusted RR 1.45; 95% CI 0.73-2.91). CONCLUSION: Although of limited size, this audit suggests that long preoperative delay in patients with peptic ulcer perforation is associated with factors related to both the internal organisation of the healthcare system, the patient's pathological picture, and the quality of diagnosis and treatment given.

Patient perception and assessment of admission to acute cardiac care unit.

BACKGROUND: To provide equal care and treatment of cardiac patients it is common practice to base the work on clinical guidelines. These guidelines mainly cover the provider perspective rather than the patient perspective. Patient satisfaction, however, is an important parameter within quality development of professional services in hospitals. Patient satisfaction is, i.e. connected with the amount of information provided to the patient and how much patients are involved in their care and treatment. This is also assumed to apply within cardiac practice. However, in relation to acute admission there is no clear picture of the patients' real preferences; likewise there is no documentation whether these preferences correspond with the nurses' assumptions. AIM: The aim of this study was primarily to investigate what preoccupied patients admitted to cardiac care units with acute coronary syndrome in connection with the first hours of their admission, and secondly to discuss these perceptions in relation to the nurses' perception from a previous pilot study. METHOD: A qualitative descriptive analysis of 30 semi-structured interviews was carried out to investigate the patient perception and assessment of care and treatment by acute admission. RESULTS: The patients included 22 men and 8 women with an average age of 59 (SD=11.5) years. In all, 5 themes: efficiency, professionalism, pain management, compassionate nursing and information were considered essential and all together they expressed what preoccupied the patients. CONCLUSION: It is possible to show what the patients think is important, also during acute admission. In general, the patients felt they were in good hands. Most important was the care providers' competencies and that they "knew their job". The patients' experience of pain management might suggest insufficient care and treatment within this field.

30-days mortality in patients with perforated peptic ulcer: A national audit.

BACKGROUND: In 2005, The Danish National Indicator Project (DNIP) reported findings on patients hospitalized with perforated ulcer. The indicator "30-days mortality" showed major discrepancy between the observed mortality of 28% and the chosen standard (10%). RATIONALE: An audit committee was appointed to examine quality problems linked to the high mortality. The purpose was to (i) examine patient characteristics, (ii) evaluate the appropriateness of the standard, and (iii) audit all cases of deaths within 30 days after surgery. METHODS: Four hundred and twelve consecutive patients were included and used for the analyses of patient characteristics. The evaluation of the standard was based on a literature review, and a structured audit was performed according to the 115 deaths that occurred. RESULTS: The mean age was 69.1 years, 42.0% had one co-morbid disease and 17.7% had two co-morbid diseases. 45.9% had an American Association of Anaesthetists score of 3-4. We found no results on mortality in studies similar to ours. The audit process indicated that the postoperative observation of patients was insufficient. DISCUSSION: As a result of this study, the standard for mortality was increased to 20%, and the new indicators for postoperative monitoring were developed. The DNIP continues to evaluate if these initiatives will improve the results on mortality.
